To all whom it may concern:

Be it known that I, SIMON LAKE, a citizen of the United States, atpresent residing at 23 Friedrich WVilhelmstrasse, Berlin, Germany, haveinvented a certain new and useful Improvement in Drills, ofwhich thefollowing is a full, clear, and exact description.

This invention relates to an improvement in drills particularly adaptedfor use in prospecting purposes in water beds where it is necessary topenetrate the over burden or rocky bottoms of the bed of the water, butwhich may be used with equal facility in dry drilling on land for thesame purpose.

The object of the invention is to provide a drill especially adapted forrapidly cutting through the over burden, or through rock itself, inquartz mining and for lifting the samples of material and deliveringthem to the surface where the nature of the solids may be tested by anyof the well known processes.

A further object is to provide a device in which the point of the drillis given a revolve ing movement together, and simultaneously with apercussive movement, and in utilizing the same medium employed forrevolving the cutting point to lift the gold or other metals togetherwith the particles severed from the bed and delivering them upon thesurface; means being provided for accelerating the upflow of water aswell as means for furnishing a percussive movement to the drill and alsoadditional means for supplying a medium under pressure to revolve thepoint and lift and deliver the gold and other materials to and upon thesurface.

The invention comprises means for accomplishing the stated objects andothers, all as hereinafter more particularly set forth and finallyclaimed.

In the accompanying drawings, illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1, is anelevation showing diagrammatically the arrangement of my improvement.Fig. 2, is a detail elevation of the upper end of the tubes having theoperating cylinder in position and which is employed for imparting apercussive movement to the drill. Fig. 2;. a detail sectional elevationof the lower ends of the tubes. Fig. 4, is a similar view of the upperends thereof. Fig. 5, is a detail view illustrating the operation of theslide valve for controlling the supply of the operating influence to thepiston cylinder. Fig.

6, is a detail section on the line 66 of Fig. 3. Fig. 7, is a similarview on the line 77 of Fig. I 3. Fig. 8, is an end view of the cuttinghead. Fig. 9, is a detail section drawn on the line 99 of Fig. 3. Fig.10, is a'similarview on the line 1010 of Fig. 3. Fig. 11, is a sectionalperspective view of the sleeve employed for supporting the turbine. Fig.12, is a similar view of the turbine. Fig. 13, is a similar view of thecutter head. Fig. 14, shows detail views in perspective of one of themovable cutting points. In the drawings A, designates a tube whichterminates at its upper end in a head A, from which project verticallyextending arms A connected by links A to the beam of acrane B, carriedby a surface vessel B, and by which the tube and parts carried therebyare supported and suspended in a vertical position.

Operating through the tube A, and through a stuffing box A*, in thehead, is a tube C, of somewhat smaller diameter than' the tube A, andextending the full length thereof and which provides an annular space D,extending throughout the length of the tubes. Connected to the upper endof the tube is an elbow' pipe C, towhich is connected a flexible pipe D,whose opposite end is connected to a suction pump D located upon thesurface vessel and operated in any suitable manner. To the elbow is alsoconnected a piston rod E, carried by a piston head E,

a vertical reciprocating movement to the tube and the cutter carriedthereby, as will be explained later on.

The cylinder is provided with a steam chest E having an oscillatingvalve E, controlling the inlet and exhaust ports to and from thecylinder, the valve being operated by a valve rod E carried by the elbowC, .ad extending through a stul'ling box E", formed upon the steamchest.

The valve rod is provided with a double faced cam head E, upon its upperend, which alternately engages beveled projections e, and 6, extendingfrom the valve. The operation of the valve will be best understood fromthe general description of the operation of the device.

A steam pipe K, is connected to the steam chest for supplying steamthereto and exfits the interior of the tube A, and extends nearly to thelower end thereof, the sections being connected by webs F formedintegral with the sections. The section F, is somewhat shorter than theouter section F is increased in thickness at its lower end, and

' has an internal annular groove F in which H ofthe cutter end isconnected to a force is revolubly held the upper flanged end of aturbine wheel or sleeve G, having angularly arranged blades G, atitsupper end and an externally threaded flange G at its lower end.Screwed to the flange G is a cutter head H, having diametrically arraned recesses H, in each of which is pivotally held a tapering or wedgeshaped cutter H all of which cutters are designed to swing. outwardlyupon the downward movement of the cutter head to cut or bore a largerhole than and thus form a clearance space for the tube A. The lowerfaces of the cutter head between the recesses are beveled in oppositedirection, as shown at H to provide a 'plu-' rality of cutting edges andthe flange of the turbine G, is provided with a series of openings Gwhich re 'ster with openings H and ead and the pivoted cutter pointsrespectively, which permit of the escape of the water after acting uponthe turme. To the head A, of the outer tube A, is connected'a flexiblepipe I, whose opposite um I, also located upon the surfacevesse anoperated in any suitable manner and by which water is forced down underpressure through the space D between the tubes to engage the turbine.

The cutter is formed at its upper end with I a spider frame J,supporting a short vertically projecting spindle J, upon which ismounted a propeller J ,-which acts with the cutter and accelerates the uflow of the water and material cut from t e water bed.

Having described the general construction of my device, the advantagesand operation thereof will be best understood from the 'fol-' lowingdescription of the operation. Assuming the (piston is in the upper endof the cylinderan the tube C, and cutter or drill point proper, likewiseelevated. Steam is admitted 1nto the steam chest from which it escapesthrough the upper inlet port a,

and acting upon the piston will drive it downwardly to the lower end ofthe cylinder and ,through the medium of the tube will force the cuttersinto contact with the surface beexpanded steam from the upper surface ofthe piston previously to the inlet of steam to the lower part of thecylinder which, acting upon the piston, will elevate the same andlikewise the tube C, and the cutter, thus providing a reciprocatingmovement to. the tube and a percussive-action to cutter. Simultaneouslywith this operation the force and suction pumps are set in motion, andthe former, which may be stated, is connected with a suitable supply,forces water down throu h the annular space or passage D, and forcib yprojects it against the blades of the turbine, imparting a revolvingmovement thereto and likewise to the cutter, and after the water hasacted upon the turbine it passes through the openings G H and H and isdrawn up through the tube C, by the suction pump together with theparticles cut from the surface operated upon, and delivered into anysuitable receptacle provided therefor. The propeller J may be employedfor agitating and accelerating the upflow of water and material, throughthe'pi e C. The ro peller as shown is operated fiy and simu ta-. neouslywith the movement of the cutter.

It will thus be seen, I provide an exceedingly simple and highlyefficient device for accom lishing the pur ose stated, and it may be aded that suitable plants may be em- 4 ployed and used in connection'withthe drill for separating the materials and testing the nature of thesolids on board the same vessel Farrying the drill and operating meansthere- What I claim is:
